Introduction:
Bladder neck contracture (BNC) is a well-known complication after surgical treatment of prostate disease. However, there is no specific treatment algorithm for managing BNC. We present the technique and results on the use of potassium-titanyl-phosphate (KTP) laser for the treatment of BNC.
Materials and Methods:
We retrospectively reviewed the records of 20 patients who underwent KTP laser vaporization of BNC from January 2007 through September 2009 by two surgeons. Men were classified as having either recurrent (failed previous treatment), or initial BNC.
Results:
Of the 20 men, 8 were classified as having recurrent BNC. The etiology of bladder neck contracture was radical prostatectomy in 9 patients, photovaporization of the prostate in 10 patients, and transurethral resection of the prostate in 1 patient. There were no intraoperative complications. Mean postoperative follow up was 10.9 months. Men with recurrent BNC had worse outcomes compared to men with initial BNC. 4 of 8 men with recurrent bladder neck contracture versus 11 of 12 men with initial bladder neck contracture had successful outcomes. Of the men who recurred, mean time to failure was 8 months. Overall, 15 of 20 patients (75%) were successfully treated.
Conclusions:
KTP laser ablation can be an effective treatment modality for BNC. Our results suggest higher rates of success if used as an initial treatment for BNC after PVP. Although several patients had a recurrent BNC, overall time to recurrence BNC appears longer than with other treatment modalities.
